THE AXLE BEAM MAY HAVE TRANSVERSE SHEAR LINES ON THE BOTTOM OF THE AXLE FROM THE TRIMMING PROCESS.

Risk. THESE LINES, IF PRESENT, CAN PROMOTE INITIATION OF CRACKS, WHICH OVER TIME MAY POSSIBLY LEAD TO AXLE BEAM FAILURE AND A VEHICLE CRASH CAN OCCUR.

Remedy. MACK WILL NOTIFY OWNERS, INSPECT AND REPLACE ANY AFFECTED AXLE BEAMS FREE OF CHARGE. THE SAFETY RECALL BEGAN ON AUGUST 14, 2009. OWNERS MAY CONTACT MACK AT 1-800-866-1177.

Defect. ON CERTAIN TRUCKS EQUIPPED WITH PARKER SINGLE CHECK VALVES (SCV) PROVIDED BY BENDIX. THE DEFECT EXISTS IN THE PARKER SCV THAT CONNECTS WITH THE SUPPLY PORT OF THE SR-7 SPRING BRAKE MODULATING VALVE. AFTER PROLONGED USE OF THE PARKER SCV, THE VALVE BODY RETAINER MAY BECOME EXCESSIVELY WORN AND EVENTUALLY BREAK APART. PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULATING VALVE, POTENTIALLY CAUSING EITHER LEAKAGE OUT OF THE SR-7 VALVE OR PREVENTING AIR FROM PROPERLY EXHAUSTING FROM THE SR-7 VALVE.

Risk. THIS CONDITION CAN CAUSE A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER THE OPERATOR PULLS THE DASH VALVE BUTTON. THESE CONDITIONS CAN OCCUR WITHOUT WARNING, LEADING TO UNINTENDED VEHICLE ROLLAWAY, BRAKE DRAG, OR IN THE CASE OF LOSS OF PRIMARY CIRCUIT, INABILITY TO MODULATE THE SPRING BRAKES.

Remedy. MACK IS WORKING WITH BENDIX TO REPLACE THE PARKER SINGLE CHECK VALVE. THE RECALL BEGAN ON JANUARY 9, 2008. OWNERS MAY CONTACT BENDIX AT 1-440-329-9000 OR MACK AT 1-800-528-6586.

Defect. CERTAIN TRUCKS EQUIPPED WITH A FRONT GLAD HAND OPTION FAIL TO COMPLY WITH THE PERFORMANCE CRITERIA REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, 'AIR BRAKE SYSTEMS.'

Risk. THE PURPOSE OF THIS STANDARD IS TO INSURE SAFE BRAKING PERFORMANCE UNDER NORMAL AND EMERGENCY CONDITIONS.

Remedy. DEALERS WILL REPLACE THE SPRING BRAKE MODULATING VALVE FREE OF CHARGE. THE RECALL BEGAN ON OCTOBER 16, 2006. OWNERS MAY CONTACT MACK TRUCK AT 1-800-528-6586.

Defect. ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS EQUIPPED WITH HOLLAND AIR SUSPENSION SYSTEMS, A TRANSVERSE BEAM CASTING MAY FRACTURE UNDER NORMAL LOADS. IF A CASTING BREAKS WHEN THE VEHICLE IS TRAVELING ON A ROADWAY THERE IS THE POTENTIAL FOR PIECES OF THE CASTING TO BECOME PROJECTILES AND THE SUSPENSION'S TRANSVERSE BEAM MAY DROP DOWN LOW ENOUGH TO CONTACT THE ROAD SURFACE.

Risk. THIS WILL CAUSE SPARKS THAT COULD POTENTIALLY IGNITE AND CAUSE A FIRE.

Remedy. DEALERS WILL INSPECT AND REPLACE THE DEFECTIVE TRANSVERSE BEAM ASSEMBLIES. THE RECALL BEGAN ON AUGUST 19, 2005. OWNERS MAY CONTACT MACK TRUCKS AT 610-709-2131.
